Ok, found the specs for that model here
15 to 21 khz, which makes it pretty much, as I said, a "video" monitor. The lack of separated sync and the 9-pin connector labeled "RGB/TTL" pretty much gives it away.
Still might be a decent monitor, but you'll need to treat it like an arcade monitor for interfacing purposes. It's not just going thook up to a standard PC and go, like some of the 31.5khz models can.

Hmmm, mine doesn't have a separate sync input on the rgb in and it also is labeled RGB/TTL, but it is VGA capable. Mine has a 34-pin IDC connector instead of a 9-pin, though.
Since this particular one only supports up to 21kHz, it's not nearly as flexible as the one I have but it should still make a very nice arcade monitor. My NEC will plug right into a PC, jamma board, DVD player, PS2, etc.... The more flexible 15-35kHz models usually sell for around the same price as this one, I would skip this one if you are interested in hooking it up directly from a PC not using a video-out card.
